The U.S. water and wastewater treatment market size was valued at USD 106.18 billion in 2022 and is projected to grow from USD 113.08 billion in 2023 to USD 179.22 billion by 2030, exhibiting a CAGR of 6.8% during the forecast period.

Water and wastewater treatment is the process of purifying and cleaning water that is contaminated or considered unfit for consumption in different applications such as, industrial and municipal. This market includes both the purification of water before it is used for consumption and the treatment of wastewater to get rid of impurities before it is released back into the environment. Businesses in this sector offer disinfection, filtration, chemical treatment, membrane separation, and other services and technologies to remove contaminants from water and wastewater.


Disruptions in Supply Chain during the Pandemic Hampered the Market

The COVID-19 crisis arisen the need for an improvised supply chain and the adoption of flexible working ways. Traditional supply chains of water and wastewater treatment are heavily dependent on the human workforce. Thus, during the outbreak, the supply chains faced enormous challenges due to a shortage of manpower. Leading manufacturers reported supply chain disruptions, delaying orders, and impact on their businesses. As economies are reopening, the still active pandemic is challenging supply chains in terms of inventory buffers, diversity pressure, changing consumer behavior, price fluctuations, trade wars, freight imbalances, and manufacturing shifts. Supply chains are becoming costly and sometimes represent the company’s highest cost. Due to multi-country disruption, traditional supply chains lack resilience. Lack of flexibility in value chain operation is unable to meet stakeholder expectations and does not address consumer demand.

Increasing Population and Rapid Urbanization to Boost Need for Water and Wastewater Treatment

The world population is projected to reach 8.5 billion people by 2030, 9.7 billion by 2050, and surpass 11 billion people by 2100, according to a forecast from the United Nations. Furthermore, the requirement for wastewater treatment in metropolitan areas would increase due to the rising urbanization of the world. The World Health Organization (WHO) predicts that between 2020 and 2025 and 2025 to 2030, the world's urban population would increase by more than 1.63% and 1.44% per year, respectively. Over 68% of the world's population is anticipated to reside in urban areas by 2050, according to the UN.

With the increasing population, the load on available water resources has increased. Water distributing organizations are pressured to ensure citizens a clean and safe water supply. However, population growth has also increased the stress on manufacturing industries, which may lead to severe water pollution. Growing urbanization and industrialization takes a heavy toll on available water sources due to the addition of toxic minerals and chemicals.


Strict Effluent Treatment Regulations to Augment Market Growth

With production processes advancing technologically, the volume of waste water generated has increased significantly in recent years. Wastewater from companies that process rare metals, pesticides, and chemicals, among other toxic compounds harm the environment. It can have serious impact if not treated appropriately before being disposed of into freshwater sources. The U.S. Environmental Protection Agency (EPA) and other regulatory bodies have issued strict limits on the discharge of pollutants into clean water.

The U.S. EPA has also issued regulations for the Wastewater Directive for the industry as part of the Clean Water Act (CWA). The maximum level of contamination allowed at discharge depends on the type of industry, and certain values have been set according to the performance of the treatment systems. For example, the EPA published the Guidelines and Standards in 2016 for Oil and Gas Recovery, covering wastewater discharges from drilling, field exploration, well treatment, and production on land in coastal and offshore areas. The regulations provide penalties for offenders with prison sentences and heavy fines. The proliferation of such strict rules has led the industry to build and maintain wastewater treatment plants. Therefore, stringent regulations on this industry are expected to drive the U.S. water and wastewater treatment market growth in the coming years.


Highly Flammable Nature of Water and Wastewater Treatment to Restrict Market Growth

Even though there are strict regulations for water and wastewater treatment, many industries are discouraged from using advanced treatment technologies on site due to high investments in constructing the wastewater treatment plants. However, with increased competition and reduced profit margins, companies are not seeking such significant investments, leading to a slowdown in market growth. As a rule, a country's capacity to treat contaminated water and wastewater depends on its income. The treatment capacity in high-income countries is over 70% of wastewater production, compared to 8% in low-income countries. Moreover, it is also difficult to collect and process liquid waste compared to solid waste.

Wastewater management is a time-consuming and complex process. Therefore, it requires large capital and incurs high costs for operating wastewater collection and processing equipment. Wastewater handling requires skilled workers to perform different duties. As they need to work in other locations, retaining highly professional staff to carry out smooth operations can sometimes be difficult.

In addition, liquid waste easily pollutes freshwater resources or the land. Therefore, it should be handled carefully. Furthermore, wastewater treatment plants become less efficient over time due to the constant build-up in piping systems. These factors can restrict the market progress.
